When I create a vlan (say vlan 4 )in the the vlan database, I see two interfaces: 'vlan 4' and 'unrouted vlan 4' when I do a snmpwalk at the ifDescr node. The 'unrouted vlan 4' does not show up at the command show vlans. How can this be explained? Can I monitor traffic on these unrouted vlan or are they to be ignored?
